Crank & BB help

Posted on
  • Hi all,

    need a little bit of help with cranks/bb, I've never been good with sizing of hubs or cranks, measurements really are not my thing!

    I'm pretty new to the forum, so sorry if there is a dedicated thread to this

    I have two bikes, first is a old Peugeot racer, other is a Sun Solo.

    The peugeot needs new crank arms, both drive-side and non, anyone know what sizing it needs?

    Other frame is a Sun Solo, only have the BB for it, would like a new crank and BB, so sizing would be great

    Any help would be really appreciated.

  • Measure the width of the BB shell on the frame. They are probably both 68mm.

    Is the Peugeot 80's or later? It's probably British threaded.
